ABSTRACT:
An anti-skid braking method is provided for controlling braking force to be applied to a wheel of an automotive vehicle by detecting any wheel behavior that the wheel is about to lock. The method comprises the following steps: detecting a vertical acceleration of a vehicle body of the automotive vehicle; detecting a longitudinal acceleration of the vehicle body; reducing a value, which corresponds to the vertical acceleration, when the longitudinal acceleration falls into a range not smaller than a first predetermined value, whereby a correction value is computed; and lowering sensitivity, at which the braking force is to be reduced in response to the wheel behavior, in accordance with an increase in the correction value computed in the correction value computing step. The longitudinal acceleration detection step may detect accelerations of left and right wheels, and the correction value computing step may include a step of selecting, as the wheel acceleration to be subjected to the processing, the greater one of the accelerations of the left and right wheels detected above. An anti-skid braking system suitable for use in practicing the anti-skid braking method is also described.
